Hola friends! Today I baked a wonderful Tarta de Santiago, and I thought.. let’s tell them more about this flour.If you spend time in Spanish, French, or Italian bakeries, you’ll notice something. Many of the best cakes contain almonds instead of wheat flour. The Tarta de Santiago, French financiers, Italian amaretti, and macarons are all built on ground almonds.
We bake with almond flour all the time, and the Tarta de Santiago is one of our favorites. So why do Mediterranean cooks use it so often? Is it about gluten, flavor, or health? The honest answer is a little of each, and a lot of history. Let’s dig in.
What Is Almond Flour?
Almond flour is simply almonds that have been ground into a fine powder. Nothing else is added. If you buy it in a shop, the label should list almonds and nothing else.
Almond Flour vs. Almond Meal
The two are close relatives, and the difference is the skin:
| Almond flour | Almond meal | |
|---|---|---|
| Made from | Blanched almonds, with the skins removed | Whole almonds, with the skins |
| Color | Pale and creamy | Flecked with brown |
| Texture | Finer | Slightly coarser |
| Flavor | Mild | A little more bitter |
| Best for | Delicate cakes and macarons | Coatings and rustic baking |
In Spain, you’ll usually see it sold as almendra molida (ground almonds) or harina de almendra. In general, the two can be used interchangeably, but a fine, blanched flour gives the smoothest cake.
Is It Healthier Than Wheat Flour?
It’s different, rather than simply healthier. A quarter cup (about 30 grams) of almond flour has around 180 calories, 16 grams of fat, 6 grams of protein, and 2 to 3 grams of fiber. It has fewer carbohydrates than wheat flour, but it’s also much richer in fat. Because it contains no wheat, it’s naturally free of gluten. However, check the packaging, because some products are made in factories that also handle wheat.
Where Does It Come From?
Almonds are a classic Mediterranean tree crop, and they have been part of the region’s food for centuries. They originally came from Central Asia, and they reached Spain through Persia, the Arab world, and North Africa. The Arabs planted many more almond trees, and they brought sugar cane too.
Why Do Mediterranean Cooks Use Almonds?
There’s no single reason, but three stand out:
- History: almonds and sugar arrived together, so almond sweets became part of the local food culture. Marzipan, for example, was already known in the Arab world around the year 700, and it likely reached Toledo in the early eighth century.
- Availability: almonds grew in the dry, sunny hills of the region, so they were close at hand.
- Flavor and texture: ground almonds make a cake moist, rich, and dense without any butter or flour.
So what about gluten? That’s a happy side effect, not the original reason. In other words, these cakes weren’t invented to be gluten-free. They just happen to be.
The Tarta de Santiago
This Galician cake is the best-known example. According to the EU’s rules, it must be made in Galicia, and it must contain at least 33% almonds. About that…I do bake them at my own place. So I don’t hope aunty Ursula come and spank me. Sugar must be over 33% and eggs over 25%. The version without a pastry base contains no flour at all. This is my recipe.
The cake’s roots are old. The first documentary evidence dates to 1577, and food writer Claudia Roden traces it to an almond Passover cake from the 11th century. The cross on top is dusted with powdered sugar through a stencil.
Other Famous Almond Bakes
- Financiers (France): small, moist almond cakes baked in rectangular molds that look like gold bars.
- Macarons (France): the shells are built on finely ground almonds.
- Amaretti (Italy): chewy or crisp almond cookies, especially linked to Sicily.
What Does It Taste Like?
Almond flour tastes sweet, nutty, and rich. It also has a gentle buttery quality, because of the natural oil in the nuts. Blanched flour is mild and delicate. Almond meal is a little earthier, with a slight bitterness from the skins.
How to Use It in Cooking
Almond flour is a baker’s friend, but it behaves differently from wheat flour. Because it has no gluten, it can’t build a structure, so cakes are denser and moister.
Easy Ways to Use It
- Flourless cakes: such as the Tarta de Santiago, which relies on eggs for lift.
- Cookies: amaretti and macarons are the classics.
- Cakes and muffins: replace part of the wheat flour for a moister crumb.
- Coatings: use almond meal instead of breadcrumbs for fish or chicken.
- Thickening: a spoonful stirred into a sauce adds body and richness.
Baking Tips
- Don’t swap it 1:1. In a recipe built for wheat flour, replace only part of the flour, because the structure will change.
- Sift it. It clumps easily, and sifting gives a smoother batter.
- Watch the color. Almonds brown quickly, so cover the cake with foil if the top darkens early.
- Choose fresh flour. Old almond flour can taste stale.
Make Your Own
You can grind your own in a food processor. Use blanched almonds for a pale flour, and pulse in short bursts. If you blend continuously, you’ll end up with almond butter. Adding a spoonful of sugar from the recipe helps keep the powder dry.
What Can You Substitute?
If you don’t have almond flour, here are some options. Keep in mind that these are our suggestions, so expect small changes in texture.
- Ground hazelnuts: a good swap in cakes, with a toastier flavor.
- Ground walnuts or pistachios: they work in many cakes, but they change the flavor more.
- Wheat flour: use it only in recipes that call for a mix, and expect a lighter, drier crumb.
- Allergies: all of these are nuts, so if you’re cooking for someone with a nut allergy, ask before you bake.
How to Store It
Almonds are full of natural oils, so the flour can turn stale. Keep it in an airtight container. Store it in the fridge if you won’t use it soon, and check the date on the package. If it smells sharp or bitter, replace it.
